▎ 摘　　要

NOVELTY - Graphene metal composite wire comprises a graphene powder layer (1), at least two layers of foam metal sheets (2), where the edge of the adjacent foam metal sheet forms a meshing structure, and the middle of a dense graphene powder cavity layer is formed in the middle. USE - Used as graphene metal composite wire. ADVANTAGE - The graphene powder filling and compacting pressing greatly reduces the body phase resistance of the lead. After pressing the foam metal, it can keep the pressure stress needed by the graphene powder and powder conductive for a long time, it does not need additional stress maintaining mechanism or device. In the cable, graphene powder occupies the space proportion of the cable and it can be greatly improved. It can improve the upper limit of cable bearing current, improve the ability of cable conveying power. The lead is designed into flat shape, without wall the appearance of the road, and reducing the cable fixing nail amount. The joint is easy to assemble and easy to use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of graphene metal composite wire. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the graphene metal composite wire. 1Graphene powder layer 2Foam metal sheet
